How to create an Op2 file?

Hello Emanuele,

The op2 result files are created by Nastran. To obtain the result file you need:

• To perform a valid calculation that does not fail with fatal error.
• Ask the output of results in a "PLOT" file. For example:

DISPLACEMENT(PLOT,SORT1,REAL)=ALL
GPFORCE(PLOT)=ALL
STRESS(PLOT,SORT1,REAL,VONMISES,BILIN)=ALL
STRAIN(PLOT,SORT1,REAL,VONMISES,BILIN)=1
FORCE(PLOT,SORT1,REAL,BILIN)=1

• Use the option "PARAM POST -1"
  

PARAM    POST    -1

So that the output of results is done in an OP2 file (and not in an XDB file, for example).

Renaud.
